Drots, drotz or drost (one of plausible translations is: Lord High Justiciar), Danish and Swedish name of a supreme state official, with at least a connotation to administration of judiciary, who in medieval Scandinavia was often a leader in the government. Scandinavia is a region in Northern Europe. ...

The word that seems to be of German origin (Truchsess) means a butler or a leader of the household but during the Scandinavian Early Middle Age it developed into a powerful political position. The drots was responsible of administering royal justice. Other powers easily became added to the position. High Constable (riksmarsk) and Chancellor were the other officers that sometimes held the premiership. Drots held the privilege to be the Regent in minority or absence of the king.

Quite often, drots acted as a kind of a ”prime minister” who was the king’s substitute and at least officially had leadership over other officials. Less powerful drosts often went into the background in favour of the chancellors or other high officers of state. A prime minister is the most senior minister of a cabinet in the executive branch of government in a parliamentary system. ...

The office seems to have appeared in Denmark in the 1200s and a bit later in Sweden and Norway. In Sweden, it acquired the official role of "second-in-command" and regentship in he wake of the disappearance of the ancient office of Riksjarl with Birger jarl who was the last jarl. In was not quite unusual that also minor (or local) princes like Dukes, as well as royal consorts, had their own drost. Birger jarl ▶(?) (English: Earl Birger), full name Birger Magnusson of Bjälbo (1210 – October 21, 1266), was a Swedish statesman and the founder of Stockholm. ...

In all three countries the post was abolished in the 1380s. In Denmark it was replaced by the Steward of the Realm. In Sweden it was soon revived before mid-1400s and in the 17th century in a new version (riksdrots) ”drots of the Realm” became established which was also used in Denmark for a short while after 1660.

In North Western Germany the word “land drost” was used about noble district caretakers until the 1800s.
